Projecting upwardly from the central portion of the main table 20 areguide rods 21 around the lower portions of which are coiled springs 22.one end of which bears against the table and the other bears againstguide yokes 23 to which are secured bars 24, which bars are fastened tothe wrapper holding tray 25 on which the wrappers 26 a-re placedpreparatory to the operation of the machine. Bearing blocks 27 aresecured to the under side of the paper holding tray and are engaged bythe upper end of a U-shaped spring 28 the lower ends'of which are bentinto coils 29 through which pass a rod 30, which rod is mounted iribearings 31 secured to the table. A stop bar 32 is adjustably mountedupon the.

top of rod 33 and has a downwardly-projecting lug 32 which has a chiselpoint and penetrates the rear, end of the top wrappers on the tray nearthe rear edge and 42 secured to the table.

wrapp er.

the wrappers in the tray are a pair of wrapper carrying rollers 34 whichare rigidly secured upon shaft 35, which shaft. is revolubly mounted inframe '36, which frame is secured to the rearwardly extending bar 37which is pivotally attached to the operating lever 38-. This operatinglever is pivotally connected to shifting lever 39 by pin 40, which pinpasses through slot 41 in bearing This bearing passes around and back oflever 38 and limits the rearward movement thereof, and is U-shapedhaving the same kind of a slot as slot 41 in the other side thereofthrough which pin mounted on shaft 47 is adapted to engage the lower endcarrying rollers to move the top wrapper upon the carrier table 48, overone of the paired trap doors 49, of I have shown four pairs as I havefound in practice that this number is a very convenient number and asmany as are requireth In the forward movement of the carrying rollersthey are prevented from rotating by a ratchet wheel 50 rigidly securedupon shaft 35, which ratchet wheel is engaged by spring dog 51 securedto frame 36. The length of the cam and the operating lever are soarranged that as soon as the rear edge of the wrapper .of the operatinglever as the shaft is rotated and to throw the upper end forward therebycausing the wrapperhas reached the end of the trap doors furthest from Ithe center of the carrier table the cam disengages from the operatinglever, whereupon spring 43 retracts doors are the package guides 52which are so arranged that when the package is placed within the arms 52thereof that it will occupy a central position on the table by hinges 53best shown in Fig. 3 and to the rear end thereof; that is the endnearest the center of the carrier table, are pivotally secured link bars54. These link bars are pivotally secured to the trip bar 55 which has aslot 56 therein through which projects pin 57, which. pin is secured inthe carrier table as bestshown These trap doors are secured to thecarrier to-swing downwardly and away from each other.

in The lower end of trip bar 55- engages track 58 except at the pointwhich is centrallylocated oppo= site thecnter of the wrapper carryingrollers. At this point'there is a break in the track which permits thetrip bar to drop, thereby permitting the trap doors From this point; thetrack slopes upwardly as best shown in Fig. 3, so that before thecarrier table has made a quarter of turn, the trap doors are lockedagainst open- I ing downwardly, as the track prevents the trip bar frommoving downwardly except at this point.

' The article to be wrapped is placed by theoperator upon the wrapperwithin the package guide, and as the wrapper upon the carrier table. Itwill be observed that these wrapper carrying rollers are spaced farenough apart so that they'straddle the trap doors and .tl,1at it is notnecessary to have these doors. closed in or- 'der to'place a wrapper inproper position upon the carrier table. At each side of trap door 59,which for con} venience of designation 1 will call'the main trap door,

are ledges 60 which project upwardly from theface of.

the table at each side of the trap door and are adjusted at a distanceapart equal to the width of the package gnd'thickn'ess of the wrapper,so that as the package falls upon thetrap door between these ledges theedges of the wrapper will be turned upwardly and will" be brought incontact with the edges of the package.

Resting upon the table at each side of the main trap door are the topand end-edge-folding mechanism.

-Each side of the top of the wrapper and each edge of the end thereof isturned by mechanism of the same construction, but operating one sideafter the other, and this mechanism consists of the following partsoperatedin the following manner. The top plate 61 is provid ed with adownwardly and rearwardly projecting tongue 62 which rests upon thetoppf the table between guide bars 63 and 64, which. guide the tongue sothat" the' movement of the top plate shall be in a straight linedirectly across the main trap door. In the edge of the top plateadjacent the trap door is revolub'l'y mounted a roller 65 which engagesthe upturned side' of the paper wrapper at that side of the package asthe plate is moved toward the centerof the tflrp door.

If desired the edges of the top-folding plate could be rounded and theroller dispensed with, but I prefer the roller. as it gives a rollingcontact instead of a slid ing contact between the folding plate and thepaper wrapper. At each end and adjustably secured to the under side ofthe top-folding plate 61 are the edge-endfolding'runners 66and 6'7 whichare composed of two parts longitudinally and horizontally divided asbest shown in Fig. 19. As these cdge-end-fold-ing runners are all of thesame construction and operation I will mark theone shown in Fig. 19 as66 and describe it without describing the others in detail. Theserunners are preferably constructed of wood and the ends thereof adjacentthe main trap door come to a point at fseaess the dividing linebetweenthe upper and lower sections, and the points adjacent to eachother arecurved away from each other. The lower section is preferably providedwith sockets 68 in which are received pins 69, which pins: are securedin the upper section. 7 0' 'The upper sections are provided with smallbolts 70 which pass through slots 71 in the top plate so that therunners may be adjusted in the top plate closer together or furtherapart to adjust thesame to packages of different lengths. A knurlednu't'72 on the top of 7.5 bolt 7 O secures the top section securely inplace. The

' lower section if desired may be provided with a metal upturned side ofthe paper wrapper at that side or the package as the plate is movedtoward the center of the trap door. Tongue 75 is provided with side lugs79 and 80 between which is received the end of the slide oper: atinglever 81 which is pivotally mounted on the top of the table by bolt 82.he other end of this lever is provided with. a downwardly projecting pin83 which e nters a groove 84 in cam wheel 85, which. cam wheel isrigidlysecured upon shaft 47 on the outer end of which are pulleysSG, one ofwhich is fast and the other loose, upon which are received a belt, notshown, .to drive the shaft. Groove84 is irregular in shape, one-half ofthe groove lying in a plane passing through the axle-at right 109 ismoved to carry the top-folding plate over the main trap door so that theroller reaches. to a point directly, or approximately over the center ofthe trap door, and is 1-10 then caused to move backwardly to theposition it occupics when the pin is in the other part of the groove.Tongue 62 is provided with lugs 87 and 88 between which is received theend of the other slide operating lever 89 which is pivotally mounted onthe top of the 115.

center of the main trap door, as it begins to move backwardly the-ethertop-folding plate begins to inovetoward the center of the main trapdoor. The movement of these top-folding plates carrying theedge-end-folding runners folds the wrapper on the package so that itassumes the position shown in Fig. 15, with what I will upward movementthereby throwing lever 38 out of the path of movement of cam 46. hisdesirable to do this just before stopping the use of themachine, as inpractice'there will usually be three packageson the carrier table thatinust'be wrapped after the ieeding mechanism is stopped. Y

The irontvoverlzanging ledges of the discharge chute may terminateabruptly just before'tlie commencement of, the bottom ledges if desiredbut I prefer the construction shown as the top-end-flap willbepositively held while the bottom-end-flap is being turned:

The operating bar 139 ma} be held at both ends by guide lugs. I p
